Abstract

  Definition of a content package with media files and table of contents (TOC) data. The content package includes physical representation data and logical representation data for a media file (eg, stored in TOC data). The computing device stores, downloads and plays media files based on the data in the content package. Presentations within the content package (eg, a group of files) are available for extraction based on media player settings. The media file is provided for presentation to a user of the computing device or for storage by the computing device.

Description

  The present invention relates to content packages for electronic distribution.

  [0001] Existing systems provide a generic container for storing files. For example, file containers such as zips, tars, and cabs provide a means of grouping multiple files into a single file. Video exchange formats exist for grouping media files or streams into a single file.

  However, after obtaining a file in a format that conforms to an existing system, the computing device must re-authorize or reformat the resulting file for storage or playback. Among other deficiencies, existing systems lack a mechanism for providing a file container that can be easily modified and rendered (rendered) by the user.

  [0002] Embodiments of the present disclosure provide a content package for storing, downloading and playing audio and video via a digital distribution system. The first computing device retrieves a content package that stores one or more media files from the second computing device. The first computing device extracts table of contents (TOC) data from the retrieved content package. The TOC data includes physical expression data corresponding to the content package and logical expression data corresponding to the contents of the package. The first computing device stores the content package based on the physical representation data and uses the logical representation data to access one or more of the media files. The accessed media file is provided for presentation to the user of the first computing device.

  [0003] This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0005] FIG. 5 is an exemplary flowchart illustrating the operation of a computing device for retrieving and processing a content package. [0006] FIG. 6 is an exemplary flowchart illustrating loading and analysis of a content package and transfer of control to a media player. [0007] FIG. 2 is an exemplary block diagram illustrating a computer readable medium storing components for creating a content package. [0008] FIG. 2 is an exemplary block diagram illustrating a data structure corresponding to a content package.

  [0009] Throughout the drawings, corresponding reference characters indicate corresponding parts.

[0010] Referring to the drawings, embodiments of the present disclosure provide a content package 110 with at least a media file 120 for storage and playback via a digital distribution system. The media file 120 is a logical to allow physical access to the disc image (disc image) file for disc recording and playback of the media file 120 in the disc image (eg, without extraction). In order to provide both access, it is uniquely identified within the content package 110 at both logical and physical levels.

  [0011] One or more presentations that include multiple works and / or multiple versions of each work may be included in the content package 110. The presentation corresponds to a group of one or more files that store different video formats, resolutions, encryption schemes, and other features. The content package 110 has the ability to copy each presentation into the native format of the computing device 104 that is combined into a single file and to play the included media file 120 directly from the content package 110. provide.

  Referring back to FIG. 1, an exemplary block diagram shows a computing device 104 that stores a content package 110. The computing device 104 is, for example, a personal computer, a small notebook computer with media functions, a mobile computing device, a game machine, a mobile phone, a portable media player, or a digital versatile disc (DVD) player. Includes any computing device. The computing device 104 includes at least a processor 108 and a memory area 106. The processor 108 includes any size processor and is programmed to execute computer-executable instructions for implementing aspects of the present disclosure. The instructions may be executed by the processor 108, multiple processors executing within the computing device 104, or may be executed by a processor external to the computing device 104. In some embodiments, processor 108 is programmed to execute instructions such as those shown in the drawings (eg, FIGS. 2 and 3).

  [0013] The memory area 106, or other computer-readable medium, stores the content package 110. In some embodiments, the content package 110 includes one or more media files 120 and represents an optical disc image, while in other embodiments, the content package 110 includes any of the media files 120. It is not necessary to store.

  [0014] In other embodiments, the content package 110 represents a presentation that includes a group of files for rendering to the user 102, for example. The presentation may include one or more media files 120 in addition to other files such as image files, hypertext pages, and executable code. The file in the presentation may vary according to encoding characteristics such as bit rate, video format, aspect, resolution, encryption and compression. The presentation may represent a basic video file set or an enhanced video file set where the same video file is used for both presentations, but the improved video file set Includes additional files to improve interaction. In another example, the presentation represents media content with or without different television episodes, different music videos, different trailers, advertisements, extra features, songs, and the like. In a further example, the presentation includes a copy of the same file for redundancy or verification.

  [0015] Each presentation may be associated with a particular configuration of media players executing on computing device 104. For example, the configuration of the media player depends on the software capabilities of the media player and / or hardware support provided by the computing device 104 for the media player. In another example, if a configuration of media players is detected, some of the presentations are not performed.

The content package 110 further includes table of contents (TOC) data 114. In the example of FIG. 1, the TOC data 114 includes logical expression data 118. Logical representation data 118 provides file level access to the files in content package 110 and includes the directory structure of the files. The logical representation data 118 provides logical access to the media file 120 included in the disc image to allow playback of the media file 120. For example, the logical representation includes a directory of files and a file path to one or more files associated with the audiovisual work. The file may be internal and contained within the content package 110, or may be external to the content package 110 (eg, the content package 110 is within the content package 110). Including paths to files that are not stored in the. The external file path may be used to copy an external file to the content package 110 or to provide streaming access to the content during rendering of a presentation that logically contains the file.

  [0017] The content package 110 further includes physical representation data 116. Physical representation data 116 provides byte-level access to the data stream in content package 110. For example, physical representation data 116 provides physical access to a disc image file stream for disc recording.

  In an embodiment as shown in FIG. 1, physical representation data 116 is independent or separate from logical representation data 118. For example, TOC data 114 includes logical representation data 118 for content in content package 110, while physical representation data 116 results from the operation of a compression utility. However, in other embodiments, physical representation data 116 and logical representation data 118 are grouped together in TOC data 114.

  [0019] In some embodiments, the content package 110 is identified by a composite (compound content identifier). The synthesized content identifier includes a first portion that identifies one or more audiovisual works represented by the one or more media files 120. For example, the first part is a namespace identifier according to the International Standard Audiovisual Number (ISAN) numbering and metadata system. The combined content identifier further includes a second portion corresponding to at least one encoding characteristic of the content package 110.

  [0020] In some embodiments, other data is shown in the TOC data 114 and may be included with the table of contents data. For example, the content package 110 includes one or more of the following: data identifying a digital rights management system associated with the content package 110, identifying a license file for (encrypting) the media file 120 Data, data identifying a system updatable message file for digital rights management system key management, data identifying the location of a license server storing a license for access to the content package 110, And a presentation file (eg, menu, navigation content) for interaction with the user 102.

  In general, the memory area 106 is associated with the computing device 104. For example, in FIG. 1, the memory area 106 is in the computing device 104. However, memory area 106 or any data stored thereon may be any server or local to computing device 104 or remote from computing device 104 (eg, accessible via a network) or It may be associated with other computers.

  [0022] In some embodiments, the computing device 104 is associated with the user 102, and the media player application program executing on the computing device 104 receives one or more media files from the content package 110 to the user. Render to 102. In such an embodiment, computing device 104 receives content package 110 from content provider 112.

  [0023] Referring now to FIG. 2, an exemplary flowchart illustrates the operation of the computing device 104 to retrieve and process the content package 110. In the example of FIG. 2, computing device 104 is associated with user 102. However, in another embodiment, the operations shown and described in FIG. 2 are performed in an embodiment of a cloud service with one or more computing devices remote from computing device 104 of user 102.

[0024] At 202, the content package 110 that stores the media file 120 is retrieved by the computing device 104. For example, the user 102 browses a website, purchases a movie, and downloads the purchased movie. At 204, the computing device 104 extracts the TOC data 114 and stores the content package 110 based on the physical representation data 116 in the content package 110 at 206. For example, the downloaded content package 110 may be stored in internal memory while the TOC data 114 is extracted, and then the content package 110 is recorded on the DVD. Alternatively or additionally, TOC data 114 from content package 110 may be downloaded and analyzed first. The remaining data from the content package 110 is downloaded and stored in the content package 110 with a corresponding update of the physical representation of the content package 110 and then directly to the DVD according to the physical representation data 116. To be recorded. For example, the recording comprises a volume directory and file information stream that matches the intended physical sector of the disc using a version directory or presentation directory for physical image files.

  [0025] At 208, the media file 120 in the downloaded content package 110 is accessed using the logical representation data 118. The file to be accessed is determined, for example, by detecting or determining the settings (configuration, configuration) of the media player on the computing device 104. For example, media player settings may be based on media player software settings (configuration, configuration) and / or hardware settings (configuration, configuration) of computing device 104. Based on the determined settings of the media player, a corresponding presentation and file version of the media file 120 for rendering is selected.

  [0026] In other embodiments, one or more presentations are identified to the user 102 for selection. User 102 selects a desired presentation and media file 120 associated with the selected presentation is accessed at 208.

  [0027] In some embodiments, the physical representation data 116 represents the content package 110 that exists externally as a simple file to the computing device 104 or storage system. Internally, the physical representation data 116 (eg, index or directory) includes at least a TOC file (eg, stores TOC data 114) and exposes a list of files and corresponding path names. When a file is added or removed, the list of files and corresponding path names is kept locally. Media access is initiated through the TOC file, which is created externally and not updated when the file is added or removed. More precisely, the location of the file may be abstracted and referenced externally or internally using the physical directory of the content package 110.

  [0028] At 210, the media player plays, renders, presents, or otherwise provides the accessed media player file to the user 102. In an embodiment in which the accessed media file 120 includes a presentation file (eg, a menu or other navigation content) for interacting with the user 102, the media player may identify the presentation format identified in the TOC data 110. Read one or more presentation files based on the, and execute instructions associated with the presentation files to provide menu, navigation, or playback functions to interact with the user 102. Presentation files include, for example, hypertext markup language files, extensible markup language files, metadata, script files, portable intermediate language codes, binary executable application programs, and the like.

[0029] In some embodiments, the user 102 downloads additional content for inclusion in the content package 110 or for association with the content package 110 (eg, late binding). May be. For example, if the downloaded content package 110 includes media files associated with a television program, the user 102 may later download subtitles, subtitles, soundtracks, foreign language tracks, or other related content. . User 102 may also download additional TOC data (eg, a second TOC file) associated with the additional downloaded content if the presentation was not included in the previously downloaded TOC data 114. Also good. The computing device 104 adds additional downloaded content to the downloaded content package 110 and logically combines the second TOC data with the TOC data 114 (eg, first TOC data) associated with the content package 110. To merge. The result is a single content package 110 with additional TOC data and referenced presentation files. In such an embodiment, content provider 112 may have separate media files or content packages 110 (eg, some with foreign language tracks, some with subtitles, each with different media files 120). Etc.) is not necessary. From the user experience, the user 102 downloads only the desired additional content rather than another complete content package 110 or file, saving time, bandwidth and other transmission costs.

  [0030] The content package 110 is also for exchanging media files between distribution servers in the same format used to upload and download media files from a digital distribution system to a consumer media player. Used for.

  [0031] Referring now to FIG. 3, an exemplary flowchart illustrates the loading and analysis of content package 110 and the transfer of control to a media player through flowchart 300. Discovery, filtering or other activities are performed at 310 (eg, by user 102) to identify, select, and obtain a package file, such as content package 110, at 320. The package may include a complete set of files and presentation information. The TOC data in the package may list additional files available online instead of in the package for later resource delivery and encapsulation at 330. The package file only contains the TOC file and may therefore be small compared to the size of the audio and video files. In this example, it is realistic to distribute a large number of packages via a low-capacity method such as attaching an e-mail. The consumer or device associated therewith may determine what size media file is desired for download.

  [0032] A package parser or loader (eg, associated with a media player) accesses a package file at 340 and a presentation selection at 350 (eg, a set of files including at least one of the media files 120). ). Presentation choices include a globally unique identifier, a multipurpose Internet Mail Extension (MIME) type, a file extension, or a format identifier string (eg, name and version number) that is recognized as compatible by the media player. It happens by matching. The package parser further performs a setup operation and starts playback on the media player on the computing device 104.

  [0033] In the example of FIG. 3, the package file is a presentation file (eg, an extensible mark) that describes, at 360, resource marshaling, player initialization, and application loading and starting. Up language documentation). In some embodiments, the presentation file includes metadata such as a list of resources, branching resource alternatives, and a start command string. The list of resources includes package files and network (eg, Internet) resources for initiating presentation. Presented and listed resources may also obtain and reference other resources once started. Branching resources are resource choices for the computing device 104 and user settings such as language, bit rate, resolution, codec, digital rights management, network availability and alternative files selected by bandwidth. (Configuration, configuration). In some embodiments, resource options are selected at load time, before starting.

  [0034] The launch string identifies the initial resource (eg, playlist or executable application program) that is used to initiate playback of the selected presentation by the media player. In some embodiments, there is one file and / or additional parameters in the start string to construct the start command. In other embodiments, the starting string is a single file name.

  [0035] At 380, an application program, such as a media player, opens the presentation file and performs operations such as device or presentation specific settings. For example, media players can have video resolution, language, bit rate, network connection status and speed, local storage capabilities, graphics rendering capabilities, number of decoders, supported codecs, supported digital rights, etc. Resources may be selected based on The media player performs resource placement at 370 by aligning resource files according to device specific settings. Another computing device 104 has a storage manager that allows in-place access from package files on the hard disk, and yet another computing device 104 has resources to its own device directory. While using file extraction and using a storage system before starting, some computing devices 104 load package files into the file cache for in-place access.

  [0036] Resource file marshalling is included in packages stored in their locations as well as copying distributed file systems, servers and network resources stored on the Internet (eg, at 390). Includes copying files. The generalized Uniform Resource Identifier (URI) syntax (syntax), in addition to the domain name service and web resolution mechanism, includes actual local and network file locations (eg, relative or absolute). Path) or runtime resolution for files currently stored inside a local or remote package. For example, relative references may be converted to absolute references at runtime.

  [0037] During resource alignment, resource availability is identified, actual storage locations are resolved, network connections are established, package files are copied to runtime locations, and raw The file is copied to the runtime location and the file is extracted from the package file as appropriate (e.g., once executed, before starting, other resources can be interactively resolved and obtained by the presentation itself) To extract resources for use).

  [0038] After the resources are aligned, a start player command is executed at 392 for transfer of control to the media player. The setup file processor reads the start string in the setup file and constructs a command call suitable for the computing device 104 and media player to play the media. For example, the start string is the name of a playlist or executable file (eg, the call is configured as “RUN./filename.exe-auto-x” in this example).

  [0039] At 394, control is transferred to the native media player and its storage management and rendering system. In the example of FIG. 3, the media player may use a digital rights management (DRM) protection, system revocation message (SRM) or other to disable the resource's DRM key, verification / tamper evidence, authentication and conditional access. Involved in the file. The media player uses a package header field that indicates the system, key, hash and checksum. Media players and memory management are involved in some embodiments in the termination and cleanup of packages, resources and runtime environments. The external content manager shown handles library management of stored packages: deletion after playback, or retention in a library with some automatic and user-controlled content management system.

[0040] Referring now to FIG. 4, an exemplary block diagram illustrates a computer-readable medium 402 that stores components for creating a content package 110. FIG. The example embodiment of FIG. 4 is directed to a disc image file having an additional logical layer pointing to the included file. The logical layer is in this example substantially a file container within a file container. The byte stream may be used directly for recording, but a logical reference to a file in the disc image may be used for playback.

  [0041] The computer-readable medium 402, or other memory area, further stores computer-executable components for implementation of aspects of the present disclosure. Exemplary components include a byte stream index component 404, a directory component 406, a container component 408, and an interface component 410. The byte stream component 404 determines a physical representation of a disc image having a plurality of media files 120. Directory component 406 generates a logical representation of media file 120. The container component 408 creates a content package 110 for the disc image. The content package 110 includes a media file 120, a physical representation and a logical representation. The container component 408 further identifies the encoding characteristics of the disc image, and based on the identified encoding characteristics and based on the logical representation of the media file 120 generated by the directory component 406, Defines the content identifier synthesized for the image.

  [0042] The interface component 410 provides the content package 110 created by the container component 408 for access by the computing device 104. For example, the interface component 410 provides or otherwise makes the content package 110 available for download by the computing device 104 over a network such as the Internet.

  [0043] Referring now to FIG. 5, an exemplary block diagram shows a data structure 500 corresponding to the content package 110. As shown in FIG. The data structure 500 is a logical identifier of a work that does not depend on the digital encoding in addition to a file identifier that represents digital encoding characteristics such as a moving image format, resolution, compression, and encryption for identifying playback compatibility. A combined content identifier 510 that combines various identifications (eg, titles). A table of contents 520 is stored. Presentation 1 directory information 530, structural metadata 540, digital rights management data 550, descriptive metadata 560, and file stream 570 represent fields in data structure 500.

[0044] In some embodiments, the data structure 500 is further used for selection, presentation and rating information for screening the platform on which the content package 110 is executed, automatic filtering and selection. A set of keywords and descriptive metadata that can be used (eg, genre, style, date and artist), extensions to authenticate and decrypt included files, and virtual or actual storage locations (eg, portable) File path information for included files that can be used by the device storage manager for runtime resolution of storage device) and application content references.
Example
[0045] In one example, the content package 110 is bootable. An example boot sequence is described next. The descriptor in the content package 110 indicates that the content package 110 is bootable, and the TOC data 114 is examined to identify the best presentation available to the computing device 104. The byte extent of the selected setup file is read and provided to the selected media player for execution (eg, as a start pointer).

[0046] The media player collects resources, such as by reading the resources from the package file, finding the resources locally or over the network. The media player decides when to start, loads the resource and executes the resource according to the pointer to the first resource. In some cases, the media player has “executable” code. In other cases, the initial resources are native binaries, scripting languages, markup, etc., and some linking, interpretation or compilation occurs to control the presentation.

  [0047] In some aspects of the present disclosure, the content package 110 is used to deliver resources and lacks a presentation (eg, any media file 120 or other file). There are resources as separate files that are referenced by a manifest or manifest that is embedded in the application (for example, some resources are listed in the inventory while the application program is running) , Others can be discovered and resolved). Examples include recorded personal video recording (PVR) streams, backed-up DVD streams, download or progressive download Internet stream files, and media files 120 on the local hard disk.

[0048] Some embodiments consider security and authentication. Individual files referenced by the TOC data 114 are hashed, signed and / or encrypted for authentication, tamper protection and copy protection. If the digital rights management method is supported, the TOC data 114 contains the digital rights management method for reading the file, the signed summary for verifying the file contents, and the rights to authenticate and optionally decrypt the signature. Identify any information to link to the certificate.
